摘　　要：分析了现PTN的典型组网架构,探讨了城域LTE承载的主要保护方式,详细比较了ECMP保护模型与现VRRP/IP FRR保护方式,提出的ECMP保护模型能有效地优化网络性能、提高网络效率。It analyzes the typical networking architecture of PTN network, and discusses the main protection for LTE transmission. On this basis, the Equal-Cost Multipath Routing（ECMP）protection model of PTN network is proposed. It makes a comparison between ECMP protection model and VRRP/IP FRR protection model. The results show that network performance and efficiency is greatly improved by ECMP protection.
